Referring to FIGS. 1 and 2, a beauty instrument with mask 10 according to a first embodiment is provided. The beauty instrument with mask 10 includes a flexible mask 100 and a controller 200 for controlling the flexible mask 100. The flexible mask 100 includes a first flexible layer 102 and a second flexible layer 106 overlapped with each other (for clarity of display, in FIG. 1, the first flexible layer 102 and the second flexible layer 106 are separately shown), the first flexible layer 102 and the second flexible layer 106 have corresponding eye and mouth openings (not labeled). The flexible mask 100 further includes a plurality of functional layers 104 sandwiched between the first flexible layer 102 and the second flexible layer 106, the plurality of functional layers 104 are symmetrically distributed or regularly distributed, and a plurality of electrodes 108, each of the plurality of electrodes 108 is electrically connected with a single functional layer 104 or a pair of functional layers 104. If a quantity of the plurality of electrodes 108 is defined as K (K=1, 2, 3, 4, 5 . . . ), then a quantity of the plurality of functional layers 104 is 2K (K=1, 2, 3, 4, 5 . . . ) or K. The controller is electrically connected to the K electrodes 108, and the plurality of functional layers 104 in the flexible mask 100 are controlled by the K electrodes 108. In one embodiment, according to FIG. 1, the quantity of the plurality of functional layers 104 is 8 (2K), for example, the quantity of the plurality of electrodes 108 is 4 (K). Each electrode 108 is electrically connected with two functional layers 104. Two ends of the electrode 108 are separately connected with the two functional layers 104. The two functional layers 104 electrically connected with the electrode 108 are symmetrically located on two sides of a user's face. Each of the plurality of functional layers 104 comprises a graphene layer.

At least one functional layer 104 can be a plurality of functional layers 104, or one functional layer 104. As shown in FIG. 1, the flexible mask 100 includes 8 functional layers 104. The 8 functional layers 104 are symmetrically distributed at a cheek position of a human face. When the flexible mask 100 includes a plurality of functional layers 104, the position of the functional layer 104 is not limited, and can be a forehead position, a cheek position, an eye below position, a nose position, or the like. The number of the functional layers 104 is not limited and can be adjusted as needed, and may be 2, 8, 15, 20, or the like. An area of each functional layer 104 is not limited and can be adjusted as needed. Adjacent functional layers 104 are spaced apart and insulated from each other.

The controller 200 includes a plurality of function buttons for controlling the flexible mask 100. The controller 200 is electrically connected to the flexible mask 100 through the plurality of electrodes 108. The controller is used to input a voltage between two of the plurality of electrodes 108 to produce current in the plurality of functional layers 104. A circuit is formed between the controller, the two of the plurality of electrodes 108, the plurality of functional layers 104 electrically connected with the two of the plurality of electrodes 108, and the face skin of the user. As such, the current flows through the controller, the two of the plurality of electrodes 108, the plurality of functional layers 104 electrically connected with the two of the plurality of electrodes 108, and the face skin of the user. Each of the plurality of function buttons can control the current magnitude, the frequency of the current, the position of the input current, etc., to control the plurality of functional layers 104 inside the flexible mask 100. The flexible mask 100 can be movably coupled to the controller 200. Optionally, the first flexible layer 102 or the second flexible layer 106 can include a window 110, and the plurality of electrodes 108 are exposed from the window 110 and electrically connected to the controller 200 via a plurality of lead wires 108 a. The window 110 is provided with an access port through which the controller 200 is connected to the flexible mask 100. The flexible mask 100 can be replaced as needed. The flexible mask 100 can also be cleaned for reuse.

A material of the first flexible layer 102 or the second flexible layer 106 can be a flexible material such as non-woven fabric, silk, flexible cloth, porous flexible paper, or silica gel, and can be directly attached to a person's face. A thickness of the first flexible layer 102 or the second flexible layer 106 can be set according to actual needs. In this embodiment, the thickness of the first flexible layer 102 or the second flexible layer 106 is in a range from 10 to 100 micrometers. In use of the beauty instrument with mask, the second flexible layer 106 will be directly attached on a face. The second flexible layer 106 is a porous structure.

A material of the electrode 108 can be metal, alloy, indium tin oxide (ITO), antimony tin oxide (ATO), conductive silver paste, conductive polymer or conductive carbon nanotube. The metal or the alloy can be aluminum, copper, tungsten, molybdenum, gold, titanium, rhodium, palladium, iridium or any alloy thereof. In this embodiment, the K electrodes 108 are all copper wires with a diameter of 1 micrometer. Preferably, an insulating layer can be coated on the surface of each of the K electrodes 108. A material of the insulating layer can be a flexible material.

Each electrode 108 corresponds to one functional layer 104 or two functional layers 104. When one electrode 108 corresponds to one functional layer 104, one end of the electrode 108 is electrically connected to the functional layer 104, and the other end is electrically connected to the controller. In this case, the controller can control the one functional layer 104 through the one electrode 108. The numbering of the one electrode 108 corresponds to the numbering of the one functional layer 104. When one electrode 108 corresponds to two functional layers 104, two ends of the electrode 108 are separately electrically connected to one of the two functional layers 104, and a middle part of the electrode 108 is electrically connected to the controller. In this case, the controller can control the two functional layers 104 simultaneously, and the numbering of the one electrode 108 corresponds to the numbering of a pair of functional layers 104. The two functional layers 104 electrically connected with the same electrode 108 have the same numbering. The numbering order of the plurality of electrodes 108 does not represent the position order. That is, the positions of two electrodes 108 with neighbor numbering may be adjacently or at intervals. Since the numbering of the electrode 108 corresponds to the numbering of the functional layer 104, it can be understood that the positions of two pairs of adjacent functional layers 104 or the two adjacent functional layers 104 with neighbor numbering may be adjacently or at intervals. Referring to FIG. 1, in this embodiment, one electrode 108 corresponds to a pair of functional layers 104, and the flexible mask 100 includes four pairs of functional layers 104. Referring to FIGS. 3A to 3D, for example, the four pairs of functional layers 104 are numbered 1, 2, 3, and 4, positions 1, 2, 3, and 4 can be arbitrarily set.

The plurality of functional layers 104 can only include the graphene layer. The graphene layer includes at least one graphene. In one embodiment, the graphene layer is a pure structure of graphenes. The graphene layer structure can include a single graphene or a plurality of graphenes. In one embodiment, the graphene layer includes a plurality of graphenes, the plurality of graphenes is stacked with each other and/or located side by side. The plurality of graphenes is combined with each other by van der Waals attractive force. The graphene layer can be a continuous integrated structure. The term “continuous integrated structure” can be defined as a structure that is combined by a plurality of chemical covalent bonds (e.g., sp² bonds, sp¹ bonds, or sp³ bonds) to form an overall structure. A thickness of the graphene layer can be less than 1 millimeter.

Each of the plurality of functional layers 104 can further include a carbon nanotube layer overlapped with the graphene layer. The carbon nanotube layer and the graphene layer can be two separated layers. The carbon nanotube layer includes a plurality of carbon nanotubes joined by van der Waals attractive force therebetween. The carbon nanotube layer can be a substantially pure structure of carbon nanotubes, with few impurities. The carbon nanotube layer can be a freestanding structure, that is, the carbon nanotube layer can be supported by itself without a substrate. For example, if at least one point of the carbon nanotube layer is held, the entire carbon nanotube layer can be lifted while remaining its structural integrity.

The carbon nanotubes in the carbon nanotube layer can be orderly or disorderly arranged. The term ‘disordered carbon nanotube layer’ refers to a structure where the carbon nanotubes are arranged along different directions, and the aligning directions of the carbon nanotubes are random. The number of the carbon nanotubes arranged along each different direction can be almost the same (e.g. uniformly disordered). The disordered carbon nanotube layer can be isotropic, namely the carbon nanotube layer has properties identical in all directions of the carbon nanotube layer. The carbon nanotubes in the disordered carbon nanotube layer can be entangled with each other.

The carbon nanotube layer including ordered carbon nanotubes is an ordered carbon nanotube layer. The term ‘ordered carbon nanotube layer’ refers to a structure where the carbon nanotubes are arranged in a consistently systematic manner, e.g., the carbon nanotubes are arranged approximately along a same direction and/or have two or more sections within each of which the carbon nanotubes are arranged approximately along a same direction (different sections can have different directions). The carbon nanotubes in the carbon nanotube layer can be selected from single-walled, double-walled, and/or multi-walled carbon nanotubes. The carbon nanotube layer may include at least one carbon nanotube film. In other embodiments, the carbon nanotube layer is composed of one carbon nanotube film or at least two carbon nanotube films. In other embodiment, the carbon nanotube layer consists one carbon nanotube film or at least two carbon nanotube films.

In one embodiment, the carbon nanotube film can be a drawn carbon nanotube film. Referring to FIG. 4, a drawn carbon nanotube film includes a number of successive and oriented carbon nanotubes joined end-to-end by van der Waals attractive force therebetween. The drawn carbon nanotube film is a freestanding film. Each drawn carbon nanotube film includes a number of successively oriented carbon nanotube segments joined end-to-end by van der Waals attractive force therebetween. Referring to FIG. 5, each carbon nanotube segment 143 includes a number of carbon nanotubes 145 substantially parallel to each other, and joined by van der Waals attractive force therebetween. Some variations can occur in the drawn carbon nanotube film. The carbon nanotubes in the drawn carbon nanotube film are oriented along a preferred orientation. The drawn carbon nanotube film can be treated with an organic solvent to increase mechanical strength and toughness of the drawn carbon nanotube film and reduce coefficient of friction of the drawn carbon nanotube film. A thickness of the drawn carbon nanotube film may range from about 0.5 nanometers to about 100 micrometers. The drawn carbon nanotube film can be used as a carbon nanotube layer directly.

The carbon nanotubes in the drawn carbon nanotube film can be single-walled, double-walled, and/or multi-walled carbon nanotubes. The diameters of the single-walled carbon nanotubes may range from about 0.5 nanometers to about 50 nanometers. The diameters of the double-walled carbon nanotubes may range from about 1 nanometer to about 50 nanometers. The diameters of the multi-walled carbon nanotubes may range from about 1.5 nanometers to about 50 nanometers. The lengths of the carbon nanotubes may range from about 200 micrometers to about 900 micrometers.

The carbon nanotube layer may include at least two stacked drawn carbon nanotube films. The carbon nanotubes in the drawn carbon nanotube film are aligned along one preferred orientation, an angle can exist between the orientations of carbon nanotubes in adjacent drawn carbon nanotube films, whether stacked or adjacent. An angle between the aligned directions of the carbon nanotubes in two adjacent drawn carbon nanotube films may range from about 0 degrees to about 90 degrees (e.g. about 15 degrees, 45 degrees, or 60 degrees).

In other embodiments, the carbon nanotube film can be a flocculated carbon nanotube film. Referring to FIG. 6, a flocculated carbon nanotube film may include a plurality of long, curved, and disordered carbon nanotubes entangled with each other. Furthermore, the flocculated carbon nanotube film can be isotropic. The carbon nanotubes can be substantially uniformly dispersed in the flocculated carbon nanotube film. Adjacent carbon nanotubes are acted upon by van der Waals attractive force to obtain an entangled structure with micropores defined therein. Because the carbon nanotubes in the flocculated carbon nanotube film are entangled with each other, the carbon nanotube layer employing the flocculated carbon nanotube film has excellent durability, and can be fashioned into desired shapes with a low risk to the integrity of the carbon nanotube layer. A thickness of the flocculated carbon nanotube film may range from about 0.5 nanometers to about 1 millimeter.

Referring to FIG. 7, in other embodiments, the carbon nanotube film can be a pressed carbon nanotube film. The pressed carbon nanotube film is formed by pressing a carbon nanotube array. The carbon nanotubes in the pressed carbon nanotube film are arranged along a same direction or along different directions. The carbon nanotubes in the pressed carbon nanotube film can rest upon each other. Adjacent carbon nanotubes are attracted to each other and are joined by van der Waals attractive force. An angle between a primary alignment direction of the carbon nanotubes and a surface of the pressed carbon nanotube film is in a range from 0 degrees to 15 degrees. The greater the pressure applied, the smaller the angle obtained. In one embodiment, the carbon nanotubes in the pressed carbon nanotube film are arranged along different directions, the carbon nanotube layer can be isotropic. A thickness of the pressed carbon nanotube film may range from about 0.5 nanometers to about 1 millimeter.

The graphene layer and/or the carbon nanotube layer has a better flexibility than the first flexible layer and/or the second flexible layer. When graphene layer and/or the carbon nanotube layer is used as the functional layer in the flexible mask, the flexibility of the entire flexible mask is not decreased by the functional layer. The graphene layer and/or the carbon nanotube layer has a large strength, as such, no matter how the flexible mask is bent or pulled, and the graphene layer and/or the carbon nanotube layer is not damaged.

A beauty instrument with mask according to a second embodiment is provided. The beauty instrument with mask comprises a flexible mask and a controller. Referring to FIG. 8, a flexible mask 200 includes a first flexible layer 202 and a second flexible layer 206, the first flexible layer 202 and the second flexible layer 206 are stacked with each other. The flexible mask 200 further includes a plurality of functional layers 204 sandwiched between the first flexible layer 202 and the second flexible layer 206 and a plurality of electrodes 208 electrically connected with the plurality of functional layers 204. In this embodiment, a quantity of the plurality of functional layers 204 is 12, and a quantity of the plurality of electrodes 208 is 6. Each of the plurality of electrodes 208 is electrically connected with a pair of functional layers 204. As shown in FIG. 8, there are 6 functional layers 204 symmetrically located on a cheek position, and 6 functional layers 204 symmetrically located on a forehead position.

Other characteristics of the beauty instrument with mask in the second embodiment are the same as that of the beauty instrument with mask in the first embodiment.

Referring to FIG. 9, a flexible mask 300 includes a first flexible layer 302 and a second flexible layer 306, the first flexible layer 302 and the second flexible layer 306 are stacked with each other. The flexible mask 300 further includes a plurality of functional layers 304 sandwiched between the first flexible layer 302 and the second flexible layer 306 and a plurality of electrodes 308 electrically connected with the plurality of functional layers 304. In this embodiment, each of the plurality of electrodes 308 is electrically connected with a single functional layer 304. As shown in FIG. 9, there are 8 functional layers 304 symmetrically located on a cheek position, and 8 electrodes 308 are electrically connected with the 8 functional layers 304 in a one by one manner.

Other characteristics of the beauty instrument with mask in the third embodiment are the same as that of the beauty instrument with mask in the first embodiment.

Referring to FIG. 10, the present disclosure further provides a method of using a beauty instrument with mask, the method comprises the steps of:

Step S1: providing a beauty instrument with mask, the beauty instrument with mask comprises a flexible mask and a controller;

Step S2: applying the flexible mask on a user's face; and

Step S3: turning on the controller and selecting a function button on the controller, inputting a current to a plurality of functional layer in the flexible mask, and stimulating face skin with the current.

In step S1, the beauty instrument with mask is any one of the beauty instrument with masks discussed above.

Alternatively, before step S2, the flexible mask can be further infiltrated with a liquid, that is, before the flexible mask of the beauty instrument with mask is applied on the user's face. The liquid can be a cosmetic liquid.

In step S3, the controller includes a plurality of function buttons for controlling the flexible mask. Each of the plurality of function buttons is used to control the functional layer inside the flexible mask to achieve the stimulating function. Each of the plurality of function buttons can be configured to control a current magnitude, a current frequency, a position of the functional layer which the current is input. The controller can input current to at least two functional layers via two electrodes. As such, the controller can control the functional layer inside the flexible mask to simultaneously stimulate the face skin, or selectively control a certain functional layer or some certain functional layers to simultaneously stimulate the face skin. For example, when the functional layers are located at a forehead position, a cheek position, and a chin position, the controller can control the functional layers in the above positions to circulate stimulate the face skin in the order of the forehead position, the cheek position, and the chin position.

In use of the beauty instrument with mask, a voltage is applied to two pairs of functional layers or two functional layers via two electrodes, and a micro-current will be input through the two electrode to the two pairs of functional layers or the two functional layers, and face skin between or under the two pairs of functional layers or the two functional layers will be stimulated by the micro-current. The voltage applied on each two electrodes can be kept for a power-on time, and the voltage is stop for a dwell time, then the voltage is applied to another two electrodes for another power-on time. The voltage can be applied to two electrodes in an order 1 and 2, 2 and 3, 3 and 4 . . . K−1 and K (K is the numbering of each electrode), so that the two pairs of functional layers corresponding to each two electrodes are cyclically input current, and the face skin corresponding the two pairs of functional layers are cyclically stimulated. The numbers of the two pairs of functional layers are adjacent, such as numbers 2 and 3, which does not mean that the positions of the two pairs of functional layers are adjacent. The positions of the two pairs of functional layers adjacent to each other can be arbitrarily set according to actual needs. Referring to FIG. 3A to FIG. 3D, in these embodiments, each electrode 108 corresponds to a pair of functional layers 104, and the flexible mask 100 includes four pairs of functional layers 104. The four electrodes 108 are numbered 1, 2, 3, and 4, and the four pairs of functional layers 104 are numbered 1, 2, 3, and 4. Positions 1, 2, 3, and 4 can be arbitrarily set, for example, 3A to 3D in FIG. 3. In the application, the electrodes 108 are energized according to the circulation pattern of the electrodes numbered 1 and 2, 2 and 3, and 3 and 4, thereby sequentially or selectively generating micro-currents in the two pairs of functional layers, which in turn stimulate the face skin.

In one embodiment according to FIG. 3B, in use of the beauty instrument with mask, the electrodes 108 are energized according to the circulation pattern of the electrodes numbered 1 and 2, 2 and 3, and 3 and 4, thereby sequentially or selectively generating micro-currents in the two pairs of functional layers, which in turn stimulate the face skin. In this embodiment, the power-on time of each pair of electrodes 108 is 1 s and the dwell time is 1 s. That is, with a cycle of 2 s, the power is first applied for 1 s, and then stopped for 1 s, and this cycle is performed. Among them, the voltage applied on each two electrodes is in a range of 20V-36V and the frequency of the voltage is 90 Khz.

The flexible mask discussed above can be movably coupled to the controller. The flexible mask defines an access at the window position on the first flexible layer or the second flexible layer, and the controller is connected to the flexible mask through the access. The flexible mask can be changed as needed. The flexible mask can also be cleaned to achieve re-use purpose.

Compared with the prior art, the beauty instrument with mask provided by the present disclosure has several advantages. First, it can directly fit on a user's face without the need to hold it by hand, which frees the user's hands. Secondly, through controlling a circuit by the controller, the skin on the user's face can be selectively stimulated, and the face parts to be stimulated can be selected more accurately without causing facial asymmetry. Third, the carbon nanotube layer is used as the functional layer, the carbon nanotube layer has a better flexibility than the first flexible layer or/and the second flexible layer, and the flexibility of the entire flexible mask will not be reduced due to the setting of the functional layers. The flexible mask can fit on the user's face well, and the user has a high comfort degree. Fourth, the carbon nanotube layer is used as a functional layer, a strength of the carbon nanotube layer is relatively large. No matter how to bend and pull or clean the flexible mask, the carbon nanotube layer will not be damaged, and the flexible mask has a long life.

Depending on the embodiment, certain blocks/steps of the methods described may be removed, others may be added, and the sequence of blocks may be altered. It is also to be understood that the description and the claims drawn to a method may comprise some indication in reference to certain blocks/steps. However, the indication used is only to be viewed for identification purposes and not as a suggestion as to an order for the blocks/steps.
